| Abstract | In this research, a two-stage Linear Fresnel concentrating system was studied on its energy conversion, storage and electrical application. The experimental investigation of flux distributed by the solar concentrator was done to know that optical property of the system. It was found that the average optical efficiency was 26%, at a concentration ratio of 34. Comparison with other solar concentrating system shows that optical efficiency of the present system is low. Theoretical and experimental studies on the thermal characteristic of the two stage Linear Fresnel concentrating system were done. The thermal efficiency of two stage Linear Fresnel concentrating system is 7%. The numerical model was used to predict the influences of solar radiation and optical efficiency. The concentration and solar peak efficiency of the system is low when compared with other solar concentrating technologies. Experiments on Solar Thermoelectric Generator were conducted. The maximum conversion efficiency can be obtained from this system is 0.02% when the temperature difference is 50°C and at 450 W/m2 beam radiation. The comparison with other STG system indicated that the performance of TEG coupled with the two stage Linear Fresnel concentrating system can be improved by improving the solar tracking performance. In summary, this research shows that the solar concentrator requires an accurate solar tracking to enhance the performance which will increase its applicability for heating and electricity applications. |
